Particle video revisited: Tracking through occlusions using point trajectories

AW Harley, Z Fang, K Fragkiadaki - European Conference on Computer …, 2022 - Springer
Tracking pixels in videos is typically studied as an optical flow estimation problem, where
every pixel is described with a displacement vector that locates it in the next frame. Even …

Stacked hybrid-attention and group collaborative learning for unbiased scene graph generation

X Dong, T Gan, X Song, J Wu… - Proceedings of the …, 2022 - openaccess.thecvf.com
Abstract Scene Graph Generation, which generally follows a regular encoder-decoder

A review of recurrent neural network based camera localization for indoor environments

MS Alam, FB Mohamed, A Selamat, AB Hossain - IEEE Access, 2023 - ieeexplore.ieee.org
Camera localization involves the estimation of the camera pose of an image from a random
scene. We used a single image or sequence of images or videos as the input. The output …

DKM: Dense kernelized feature matching for geometry estimation

J Edstedt, I Athanasiadis… - Proceedings of the …, 2023 - openaccess.thecvf.com
Feature matching is a challenging computer vision task that involves finding
correspondences between two images of a 3D scene. In this paper we consider the dense …
